If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

There is no hash or signature verification, the destination domain is unrelated to the package's stated publisher, and the staged file uses a hidden dot-name. The dropper code uses obfuscation patterns inconsistent with a legitimate utility: single-letter identifiers (_D, _N, _P, _F, _U, _A), a base64-encoded URL string, a forged Mozilla/5.0 macOS User-Agent, and darwin-only platform gating.
